The MTOC with microtubules radiating from it then moves from the distal surface to the proximal pole located at the former center of the sporocyte (Brown & Lemmon, 1983).
In meiosis of liverworts with quadrilobed sporocytes, division polarity is determined early in prophase I and the sporocyte becomes deeply lobed with cleavage furrows that predict the eventual planes of cytokinesis.
The members of the Jungermanniopsida all have sporocyte quadripolarity that is predicted by intersecting bands of microtubules marking the sites of the future furrows.
There is extensive cytoplasmic preparation for quadripartitioning of the sporocyte that begins well in advance of nuclear division (Fig.
53d-i) that mark the future cytokinetic planes along which the sporocyte will be cleaved into a tetrad of spores after meiosis.
The three dimensional shape of the metaphase I sporocyte is shown in Fig.
A thick wall consisting of a mucopolysaccharide of uncertain composition is laid down by the sporocyte and the cellulosic vegetative cell wall lyses releasing the sporocytes into a common spore chamber.
POs are usually associated with meiotic quadripolarity in the Jungermanniopsida where sporocytes are deeply quadrilobed (Fariner, 1895; Brown et al.
